Looks round about, finding something very ugly (7)
I believe the answer is:
eyesore
'something very ugly' is the definition.
(I've seen this before)
'looks round about' is the wordplay.
'looks' becomes 'eyes' (eyeing is a kind of looking).
'round about' becomes 'ore' (I am not sure about this - if you are sure you should believe this answer much more).
'eyes'+'ore'='EYESORE'
'finding' acts as a link.
Can you help me to learn more?
(Other definitions for eyesore that I've seen before include "Ugly item" , "Unpleasant sight" , "Hideous sight" , "bad sight" , "it looks bad" .)
